andhas for its main object :to provide an improved resil ent suspensionmeans for the engine or gear-boxunitwhich will allow such movementof theunit asis necessar in order that torque re-action or other vi rationsmaybe absorbed without being transmitted through to the chassis frame.The invention; relates" particularly to suspension means where -a barvinterconnecting spaced frame v members engages opposite Walls of theunit through resilient means, as

. is described" in British Patent specification i According .to thisinvention, thelbar has between the resilient means=andvwithinfthe unit arocking engagement with the latter. In a preferred arrangement, wherethe bar extends throughthe crank-case of the engine,

. ithas midway'between the resilient means, through which opposite wallsof the crank" case are supported from the bar, arocking e P B t gh.thcm,,are'{ formed .w-ith*ex-f f ternal concave faces. 18which-receive(resilient rings; 19, .19 of relatively rubber, these ibeing outwardly and'internally grippedby,

engagement-with means rigidly supported by the crank-case. These meansrigidly supported by the crankcase conveniently take the f forin of atube carried by the walls bifithe crank-case, thetube ends being entered"intoholes therein, in which case the bar maycarry'centrally-a;Patti-spherical collar internally engaging thetube. Thisparti-spherical collar is preferably of hard rubber, the

resilient means being soft rubber rings, and

provision may be made for its axial adjustment withrespect to the bar.In the accompanying drawing Figure 1,is an elevation of an engine andgear-box unit suspended according to the invention; p t I a Figure 2 isa transverse section, to a larger scale, taken through the forwardsuspension;

Figure-3 is a perspective View of the rear mounting.

In the construction illustrated,'the engine, J 2, clutch 3 and gear-box4 constitute an in- .tegral unit incorporating at the rear end I of thegear-box a casing 5 for a universal joint, this casing beingshown asforming the rear support. For this pur ose it has trans:

The forward suspension. means, which is 5 that-to which the presentinvention; partiouv larlyrelates, includes in. this-case'a crossbar l2rigidly interconnecting 1 the 1 chassis longitudinals: 10, 10 5 andassi-ng through .the

Centrally of the tube is arranged around the bara collar 24 of hardrubber'or other substance the surface of'which is of parti-sp'hericalshgpe and of a size to engagetheftuberinternally,

By this means a rocking engagement'is 'established between the bar'andthe unit Enid way of the resilient rings,and in the interior f; a a ofthe unit. In the present instance the 001-;

lar 24 is shown as being axially located means of a flange 25 fastjonthe bar and a Q second flange 26 formed on a spacing sleeve 27 the outerendofwhichengages the adjacent end plug 20. Thu'sthe collar can'be ad ajusted, by movement of the bar and the use of a a sleeve of different,length if necessary, and i tions are not transmitted through to thecrossbar moreover,

chassis frame. The I v serves for strengthenlng the chass1s frame.

What I claim as my lnventlon and deslre to secure by Letters" Patent ofthe'United States 1.

Ina motor-vehicle, an enginehaving a crank-case,chassislongitudinals, a bar interconnecting said chassis longitudlna'ls,said bar. passing through holes in opposite walls of'said crank-case,resilient rings interposed between saidbar and said walls, means rigidlysupported by said crank casagland"means between said, rings providing arocking engagement between said bar and said rigidlysupported means. 1

3. An engine having a crank-case, a supporting bar extending throughopposite walls of saidcrank-case, the bar engaging said opposite wallsthrough resilient -rings,fa tube supported within the engine from saidoppositewalls, and a parti-spherical collar on said bar which internallyengages said tube.
